To query the Gene Ontology (GO) annotations of a domain in the SDA database, please enter its SCOP accession number (e.g. d1te0a2), PDB code (e.g. 1TE0), gene name (e.g. DegS), or other keywords(e.g. Trypsin-like serine proteases), and click enter to view the results.


SDADB is a database of predicted annotations for structural (SCOP) domains using an integrated approach. Predicted annotations are assigned a likelihood using a Bayesian framework that combines structrue-based protein-domain mapping, InterPro domain, PSSM prfile and sequence homolog information. The SDADB database now contains 3,482,316 GO annotations for 211,282 SCOP domains with a probability >0.1. Of these, 1479,652 annotations for 204,948 domains have a probability >0.5. Also, SDADB provides protein-domain mappings for over 191,060 PDB structures.
